Where these two actually differ
- We flag Volatile organic compounds (VOC) off-gassing from adhesives on the Mephisto and not on the Oboz.
- We flag Azo dyes in textile upper, Waterproof membrane coating degradation and off-gassing, Formaldehyde in textile finishing resins and Adhesives and glues (polyurethane, epoxy) on the Oboz and not on the Mephisto.
- The Mephisto is leather, textile, rubber sole where the Oboz is Textile upper with waterproof membrane coating, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Mephisto is the one to buy.
